摘  要:
目的:对流苏(Chionanthus retusa Lindl et Paxt)花黄酮类化学成分进行分离鉴定,研究由流苏花制成的"糯米花茶"抗氧化作用的物质基础。方法:采用硅胶、凝胶(Sephadex LH-20)柱色谱以及制备高效液相色谱等技术进行分离纯化,综合运用波谱学方法鉴定化合物的结构。结果:从流苏花中共分离出10个黄酮类化合物,分别鉴定为槲皮素-3-甲氧基-7-O-α-L-阿拉伯(1→6)-β-D-葡萄糖苷(化合物1)、北美圣草素-7-O-β-D-葡萄糖苷(化合物2)、金合欢素-7-O-α-L-鼠李糖基(1→6)-β-D-葡萄糖苷(化合物3)、杨梅素-3-O-β-D-葡萄糖苷(化合物4)、木犀草素-7-O-β-D-葡萄糖苷(化合物5)、山奈酚-3-O-β-D-葡萄糖苷(化合物6)、木犀草素(化合物7)、杨梅素(化合物8)、芹菜素(化合物9)、槲皮素(化合物10)。结论:化合物1~6为首次从Chionanthus retusa Lindl et Paxt的花中分离得到,分离到的这些黄酮类物质可能是流苏花制成的"糯米花茶"具有较强抗氧化作用的物质基础。

摘  要:
Objective: To isolate and identify the chemical constituents from the flowers of Chinese Fringetree(Chionanthus retusa Lindl et Paxt). Methods: The chemical constituents were isolated and purified by sequential column chromatographies on silica gel, Sephadex LH-20 and semi-preparative HPLC, and their chemical structures were elucidated by spectroscopic methods. Results: A total of ten compounds were obtained and they were chemically identified as quercetin-3-methyl ether-7-O-α-L-arabinofranosyl(1→6)-β-D-glucopy–ranoside(1), eriodictyol-7-O-β-D-glucoside(2), acacetin-7-O-α-L-rhamnopyranosyl(1→6)-β-D-glucopyranoside(3), myricetin-3-O-β-D-glucopyranoside(4), luteolin-7-O-β-D-glucoside(5), kaempferol-3-O-β-D-glucoside(6), and luteolin(7), myricetin(8), apigenin(9), and quercetin(10), respectively. Conclusions: The compounds 1 through 6 were identified for the first time in the flowers of this plant, which have been reportedly to possess potent antioxidant capacity.
